Just got back my calculator after having memory upgraded. Works fine. One thought for anyone else thinking about this upgrade -- if it takes as long for you to enter programs as it does me, it took about 6 hours to enter the 6k programs I had in machine -- imagine how long it will take to enter 30k worth of programs.
Speaking of programs for 42S, does anyone know of a good source for HP 42S specific programs? I know there are plenty of HP 41 programs, but adapting them for 42S so as to take advantage of 42S features is not trivial.
Personally, I would love to have a 42S with lots of memory that could transfer programs to/from PC. I know that 48 and 49 series allow this, but I like small size of 42S.
